This seems to be a bug in app engine, with the way datastore_path is
interpreted. Specifically, some code treats datastore_path as relative
while other code treats it as absolute.
I think this can be fixed by changing line 207 in /google/appengine/
tools/dev_appserver_main.py from:
option_dict[ARG_DATASTORE_PATH] = value
to:
option_dict[ARG_DATASTORE_PATH] = os.path.abspath(value)
